俄语1. The diesel engine water pump uses the rotation of the screw to suck and discharge the liquid.
Due to the mutual meshing of each screw and the close fit between the screw and the inner wall of the liner, one or more sealed spaces are separated between the suction port and the discharge port of the pump. With the rotation and meshing of the screw, these sealed spaces are continuously formed at the suction end of the pump, enclosing the liquid in the suction chamber, and continuously moving from the suction chamber to the discharge end along the axial direction of the screw, sealing the air in each space. The liquid is continuously discharged, just as a nut is continuously pushed forward when the thread is rotated, which is the basic working principle of the diesel engine water pump.
2. The working principle of the diesel engine water pump is: when the diesel engine water pump is working, the liquid will enter the sealing space surrounded by the thread and the pump casing after being inhaled. When the active screw rotates, the sealing volume of the diesel engine water pump will be squeezed by the screw teeth. pressure and move in the axial direction. Since the screw rotates at a constant speed, the liquid outflow flow is also uniform.
Working principle of diesel engine water pump
The characteristics of the diesel engine water pump are: the diesel engine water pump has small loss and good economic performance. The pressure is high and uniform, the flow is uniform, the speed is high, and it can be directly connected with the prime mover.
Diesel engine water pumps can transport lubricating oil, fuel oil, various oils and high molecular polymers, and are used to transport viscous liquids. .
3. According to the size of the pump, it can transport the medium with viscosity from 37000-200000 centipoise.
Media containing particles or fibers: the particle diameter can be 30mm (not exceeding the rotor eccentricity). Fiber length can be 350mm (equivalent to 0.4 rotor pitch). Its content is generally up to 40% of the medium pit. If the solid in the medium is in the form of fine powder, the highest content can reach 60% or more and can also be transported.
